回流

These would be the thermal fluid circulated through the shelves for product heating and cooling, the refrigerant employed inside the vapor condenser cooling surface and oil vapors that may migrate back from the vacuum pumping system.

包括为产品加热和制冷的热传递液体；冷凝蒸发器内制冷剂；真空泵油的回流。

Install valve on return line of equipment to be balanced or as shown on the plans.

将阀门安装在需要平衡的设备回流管线上或计划要求的地方。

Install valve on return line of equipment to be balanced or as shown on the plans.

在需要平衡的设备的回流管线上或按照计划安排安装阀门。

The flood Protection - Shutdown valve, Junction Box, Flow Sensor, and Reduced Pressure Backflow Preventer shall be of the same manufacturer and covered by a single warranty policy.

堵漏-关闭阀，接线盒，流量感应器，和减压防回流阀应该采用同一个厂家的产品，以确保拥有唯一的质量保证。

Using the two-stream fluid model, the linear dispersion relation is derived assuming a two-dimensional spatial geometry. Two cases are considered, one is that the 2D spatial geometry is defined by the plane containing the two counterstreaming electron populations and the perturbation wave vector , and the other is that the geometry is defined by the plane being vertical to the two counterstreaming electron populations .

对高能束流和电子回流构成的双流系统，建立冷等离子体流体模型，采用简正模分析方法，分别考虑扰动波矢在平行于电流传播方向的平面上和在垂直于电流传播方向的平面上这两种情况，推导了不稳定性的色散关系。

In case you notice the water leel in the bottle has gone down to almost empty or the dripping has stopped or if a back flow of blood can be seen through the I set tube, please let us know.

如果您注意到瓶子里水的高度已经下降到快光了，或是不再滴了，或者如果可以看到固定管里有血液回流，请告诉我们。

Use a check valve or trap in the discharge line to prevent hazardous back flow into the system.

输气时应使用逆止阀或阻火器，以防止回流进入气瓶的危险。

7 Is there a point and click software tool post reflow which is linked to CAD or program data to facilitate component identification for rework?

在过回流焊时有无同CAD或程式数据相联系的软件工具来帮助实现元件的确认与返工？

Monophenyltin trichloride reacts withdicarbonyl dicyclopentadienyl titanium immediately at room temperature, but no ti-tanium-tin complex produced, and the products were diphenyltin dichloride〓 and tin or stannous Chloride. When diaryltin dihalides were used, only the chlorides and bromides reacted with 〓form the complexes containing titaninm-tin bond,〓. but the corresponding iodide complex was not found. This reaction is Sensitive totemperature,when the temperature is belw 10℃,the reaction hardly takes place,but as the temperature is above 25℃,more 〓 will be found and the reactionbecome more complex.

Ph-SnC〓室温下即可与Cp〓迅速反应，但不生成含钛一锡链的化合物，而是生成Ph〓和Sn或Sn〓二芳基二卤化锡化物中，只有氯化物和溴化物才能和〓反应生成含钛〓锡键的化合物〓相应的碘化物则不行，而且反应对温度比较敏感，低于10℃，反应几乎不能进行，而高于25〓，则会生成更多的〓，在回流条件下得不到含钛〓锡键的化合物，只能得到分解产物，〓和Sn或〓。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
